My invention relates to jambs and more specically' to metal jambs for use in doors and windows.

To install metal jambs in position, they must first be assembled, blocked up in position, and then the wall uprights and studdings placed in position and fastenedY thereto. With a jamb constructed in accordance with my invention, the jamb may be assembled and then slipped in between the wall uprights and studdings and then attached to the same. This permits vthe carpenters building the house to build the studdings and uprights in the usual manner as when wooden jambs are to be used, and then to place all of the metal jambs at once. Also, my jamb can be used to replace wooden jambs as they can be inserted in the old uprights and studdings, which is not possible with previous metal jambs.

Other objects and advantages of my invention will be apparent from the following description of the preferred embodiments thereof.

In the drawings:

Figure 1 is a perspective view of my invention.

Figure 2 is a cross section taken on the line 2-2 of Figure l showing my jamb as being inserted in the uprights before attaching thereto.

Figure 3 is a cross section taken on the line 3-3 of Figure 1 showing the jamb after attachment to the uprights.

Figure 4 is a cross section taken on the line 4-4 of Figure 1.

Figure 5 is a cross section of my invention showing molding strips installed after plastering.

Figure 6 is a cross section of a modification similar to Figure 5. r

Figure 7 is a cross section of a modification.

Figure 8 is a cross section of a modification.

Figure 9 is a perspective view of a modication.

Figure 10 is a View of the locking member used in the modifications shown in Figures 8 and 9.

Referring specifically to Figures 1, 2 and 3, a jamb constructed in accordance with my invention comprises a stamped metal jamb member I which has on one side a flange member 2 extendingrearwardly from the jamb member. In this flange 2 are nail holes 3. The jamb member I comprises two upright members and a head member 4, all identically shaped, but the head member 4 has flanges 5 and 6 with appropriate lbolt holes 1 therein which cooperate with bolt holes in the upright jamb members so that the two uprights and cross member can be bolted together.

On the opposite side of jamb member l from flange 2 is a member which forms a hook 8 extending substantially the length of the jamb member. A separate piece of sheet metal is formed into a locking member 9 having a hook I0 thereon to cooperate with the hook 8. The hooks 8 and I0 are slid together in the position shown in Figure 2, and the entire jamb assembled as shown in perspective Figure 1. This completed jamb is then slid in between uprights II and through the appropriate nail holes in the flange 2, nails I 2 are forced into the uprights I I to anchor the jamb in position. The locking member 9 is then pivoted on the hooks 8 and I0 until it is in the position shown in Figure 3, and nails I3 driven through appropriate holes in the locking member 9 into the uprights II permanently anchoring the entire jamb to the uprights II. As shown in Figure 3, the holes I4 in the locking member 9 and the flange 2 act as plaster anchors to bind the plaster I5 to the jamb and thus make' a smooth t.

In the modication shown in Figures 5 and 6, molding strips 25 of metal can be attached to the jamb by forming them with a curved hook member I6 which cooperates with the curved bend I1 on the jamb member I or the hook 8 to form one anchor for the molding strip 25. The

other end of the molding strip 25 is secured to the uprights by the nails I9.

To provide positions for the hinges of the door or window. a plate I8 is attached to one of the uprights of the jamb member I, and at this portion of the uprights the locking member 9 is cut away to provide room for the hinge.

In Figures 8 and 9 are shown a modification of my invention in which the long strips of locking member 9 are dispensed with and small tab locking members 20 provided. In this form of my invention, the hook 2l is in a square form and cooperates with the square hook 22. Gaps 23 are formed in hook 2| so that, after the jamb is positioned between the uprights, the locking members 20 can be inserted through the gaps 23, moved into a locking position, and then nailed to the uprights.

While I have described the preferred embodiments of my invention, I am not to be limited to any of the details set forth except Vas described in the following claims.

I claim:

1. In a jamb, metal upright and head members attached together to form a jamb, means extending from one side of each of said metal upright members of said jambl to attach said jamb to supporting uprights, hook means carried by the other side of each of said metal upright members of said jamb. a locking member having hook means pivota'liy engaging said first hook means. and molding strips having means to engage said jamb'at one side to anchor said strips.

2. In a jamb, the combination of metal uprights and a head member attached together to` form a complete door or Window jamb, a flange extending from one side of each of said metal uprights of said jamb to provide means to attach said j amb to one side of supporting uprights, a ange ,pivotally attached to the other side of each of said metal uprights `of said jamb for at. taching said second side Yof said jamb to said supporting uprights whereby said jamb can be completely assembled and inserted as a unit in `a door opening. l

3. In a jamb, the combination of metal "uprights and a head member attached together to form a complete door pr window jamb, afiange extending from one side of each of said metal 4 uprights of said jamb to provide means to attach said jamb to one side of supporting uprights, a hook means carried by the other side of each of said metal uprights of said jamb, an attaching member having hook means pivotally engaging Y said rst hook means whereby said jamb can be completely assembled and inserted as a unit in a door opening.4
